Abstract
This article presents methods of accident rate and accident frequency that can be used to analyze dangerous road sections on all state main roads of Latvia. The authors note that evaluation of road traffic safety level may be done using several methods. Latvia has 15 state main roads which lead through 24 out of 26 districts, and their total length in Latvia is 1740.8 km. Analysis of road traffic accident statistics was carried out basing on the data available at Road Traffic Safety Directorate for a three year time period (2005–2007). The authors calculated the critical value of accident rate for the state main roads network, determining that its numerical value is 1.81 accidents per 106 vehicle km. They conclude that the relation between traffic intensity and accident rate for the state main road network of Latvia has been achieved.
Highlights
In the world to analyse and estimate an accident situation in civil engineering many different methodologies and methods are used (Giretti et al 2009; Hoła 2009; Zavadskas, Vaidogas 2008; 2009)

Summary
In the world to analyse and estimate an accident situation in civil engineering many different methodologies and methods are used (Giretti et al 2009; Hoła 2009; Zavadskas, Vaidogas 2008; 2009). Different methods for the evaluation of sustainable safety The analysis done by authors covers the state main road network in Latvia. The function of the state main roads is to provide connections with foreign countries and capital cities of foreign countries. Latvia has 15 state main roads, they lead through 24 out of 26 districts, and their total length in Latvia is 1740.8 km. Analysis of road traffic accident statistics was carried out basing on the data available at Road Traffic Safety Directorate for the period of three years (2005–2007)
